Those early models gave Regen a bad reputation... That coil over the solenoid has nothing to do with Regen brake, it is used for DB (Dynamic Brake) and it is used instead of Regen brake.

Technology has come a long way in those controllers, while it is physically possible for the one "wheel moving forward forcing the other wheel to move backwards" if the motor is locked, the controller knows that because there would be no speed sensor pulses.

I use my Regen probably 98% of the time, and my neighborhood is all up and down roads and never had any feeling of slipping.

Of course You need to use a little common sense, if You come really fast to a down hill curve and hit the brakes hard, You would slide as well.

Sergio - I like the dynamic braking in my cart in general but on very minor downhill slopes, or flat out with my new battery pack on the open road - I do occasionally get a very mild type of hesitation at top speed (feels like a governor, not a brake) which is occasionally annoying. Any ideas on how to trick an old Regen 1 cart into thinking its not going slightly above 14-15 mph, but retain the dynamic braking?

I have only seen one picture on how the magnet was attached to the motors in those carts, and it was not very clear exactly how it was held in place.

If You can remove just one pole from the magnet, it would accomplish what You need since those carts could not go much faster anyway.

The voltage the controller used for those early speed sensors is different than the current models, so I don't think any of the speed fooling devices on the market would work (they are all powered by the speed sensor power feed from the controller).

Sergio - they are different alright....see below. Not sure how much to replace it if I mess up! I guess worst case is that I end up with no Regen - because unplugging it does exactly that. For some reason, this old cart was always a tad faster than Regen 2's and current code 3's - but I wouldn't mind squeezing that last 0.5mph out.

Too cold right now - cart is in storage at 12 degrees - but it might be an interesting "spring-readiness-prep" adventure.

My guess, though - is that Plum Quick has disabled Regen in their rebuild of that motor - only mrgolf will know the answer (and hopefully will share the info) when he does the install.

Plumb Quick did not disable regen on my regen 2 motor. It will run faster than the max speed in the controller likes. It kicks the braking in to slow the cart at about 15 mph. With the speed sensor unhooked the carts runs about 17-18 mph. It has been raining all day, I'll see what I can work out when it warms and drys a little. [ATTACH]image.jpg[/ATTACH]
